Title: Improvements in or relating to packaging machines
Inventor: RETY STEPHEN PAUL
IPC: B65B39/00
Filed: 1951-07-11
Abstract: 727,238. Packaging machines. VISUAL EFFICIENCY, Ltd. July 31, 1952 [July 11, 1951 ; Jan. 23, 1952], Nos. 16386/51 and 1827/52. Class 94 (1). [Also in Group XXX] A machine for packaging tablets or other relatively flat articles by depositing and sealing. them in pockets formed in continuous strip or web material, includes means for the controlled feeding of the flat articles in succession to a processing position in which the release of the articles from the baseof a gravity shoot or track is governed by the relative movement of a slotted element and the exit end of the shoot to bring the slot in the element into and out of a position vertically below the exit end of the shoot. One or more resiliently yieldable fingers or plungers, simultaneously with the conjunction of the slot and shoot exit, opera-. tively engages with the second article in the shoot considered from its exit end so as to permit only the lowermost article to be released from the shoot on effecting said conjunction. Tablets 10 delivered from a hopper by a pair of inclined conveyer discs pass in line down a pair of shoots 12, 13 of the kind described in Specification 727,237, [Group XXX], to means for delivering them to packaging apparatus. The delivery means comprises a right-angled element 29 carried by a leaf spring 32 connected at its upper end to the rear wall of a shoot, said element having a horizontal limb 30 slotted at 31 to allow passage of a tablet, and a pair of fingers 33 adapted to engage the penultimate tablet in the chute as the lowest drops through the slot. The delivery element 29 is oscillated by a camactuated pivoted rocking lever 36 engaging the spring 32 to drop the tablets one at a time to the bight of rotating peripherally-recessed preferably heated packaging drums 14, 15. Webs 18 of wrapping material fed between the drums 14, 15 each pass first beneath a drum 22 of heat-insulating material and having metallic studs 23 spaced peripherally thereon and being carried by a pivoted frame 21, which may be spring loaded. The drums 22 are driven in synchronism with the drums 14, 15, the studs 23 co-operating with the recesses in the drums 14, 15 to form pockets in the webs into which the tablets drop, the webs being sealed together around each tablet by the engagement of the non-recessed periphery of the drums 14, 15. A battery of parallel shoots 12, 13 capable of dealing with articles of different ranges of width may be provided, the shoots 12, 13 as a unit being laterally displaceable to the operative position. More than the two shoots 12, 13 may feed articles at the same time. A single finger, or both fingers 33, may engage the rear face of the article to hold it while the lowest drops through the slot. In an alternative construction the slotted element may slide on a table. In a further alternative construction the shoots 12, 13 may be pivoted at a position remote from the exit end and be moved into and out of a position above the slot in a stationary element.

Abstract: 597,531. Valve-amplifyiug circuits. HULLS, L. R., and WIGAN, E. R. June 28, 1945, No. 16562. [Class 40 (v)] [Also in Group XXXVI] In an apparatus for integrating a fluctuating signal voltage, a voltage in a condenser which is built up through a unilaterally conducting device in accordance with the magnitude and duration of the signal, has applied in series with it a compensating D.C, voltage equal to and increasing with it and derived from an oscilla. tory voltage. As shown, the voltage to be integrated is applied through condenser 21 to series connected diode 22 and condenser 23, the voltage across which is .taken to the control grid of pentode 26. The load current of valve 26 is passed through resistor 27 the D.C. voltage across which is measured by meter 29 and is proportional to the required integral. An .oscillating voltage is also applied to valve 26, through resistor 34 and condenser 35, and amplified to a degree dependent upon the bias supplied by condenser 23. The output from valve 26 is applied to the primary of transformer 36, the secondary of which is'in series with rectifier 37 7 condenser 40 and resistors 38, 39 across which is developed a compensating voltage equal to that across condenser 23 and which is applied to the anode of diode 22 through resistor 41. If the required integral is larger than is measurable on, the meter 29, then a thyratron may be arranged to discharge condenser 23 when full-scale deflection is reached and each similar repetition recorded by a counting device.

Title: A process for the manufacture of lactic acid derivatives from carbohydrate materials
IPC: C07C69/68
Filed: 1951-07-16
Abstract: In making lactic acid esters from molasses, raw cane juice, cane sugar or other carbohydrates of the kind containing sucrose, glucose or fructose or mixtures thereof an aqueous solution of the carbohydrate is heated with an alkali to temperature between 190 DEG and 300 DEG  C. to obtain a salt of lactic acid; acidifying the reaction product and filtering and decolourizing the solution if necessary, then subjecting the solution to treatment with an alcohol which is largely immiscible with water in such a way that the alcohol is continuously evaporated from a still, condensed, percolated through the lactic acid solution and returned, bearing the lactic acid extracted therefrom, to the still thus effecting at one and the same time the extraction of lactic acid from the solution and its conversion into an ester which can be isolated by a conventional method in a relatively pure state.  Alkalis mentioned are calcium oxide and caustic soda.  Alcohols specified are n-butyl, isobutyl and n-amyl.  Esterification proceeds in the still and on removal of excess alcohol the lactate is obtained. The extraction and esterification of the lactic acid may be carried out at atmospheric pressure or otherwise.  In examples the aqueous solutions of carbohydrate starting materials are heated in a pressure vessel with calcium oxide, the mixtures are cooled, acidified with sulphuric acid the precipitated calcium sulphate is removed and the acidified lactic acid solution is extracted and esterified in accordance with the invention.  The carbohydrate materials and alcohols employed respectively are molasses and n-butyl alcohol (I); molasses and n-amyl alcohol (II); raw sugar and n-butyl alcohol (III); raw cane juice n-butyl alcohol (IV); and molasses and isobutyl alcohol (V). The residual esters are distilled.

[Class 100 (iv).] In ink-ribbon mechanism, particularly for use in duplicating-arrangements for typewriters, of the kind described in Specification 402,484, the spool-brakes engage the faces of discs forming part of the spools, and the ribbon-feeding means may be arranged to increase the pressure of the spool-brakes for the purpose of locking the spools. The spools may be mounted in a cage which is detachably mounted in a frame connected to the carriage. The spools L, Figs. 3, 5, and 6, are revoluble on a shaft 30 in a cage M detachably mounted in a frame K which is connected to the carriage B and a paper-table I and is provided with rollers 7 running on a rail 8. The cage is provided with pins 60, 61 for engaging holes in the frame, and is provided also with securing-screws 64, 65 for engaging slotted lugs 18, 19 on the frame. The shaft is detachably mounted in the cage and is retained by a pivoted catch 32. The cage can be removed through an opening at the rear of the frame, and the spools can be removed from the cage by withdrawing the shaft. A shaft 41 mounted in arms 40, 40a on the cage carries loose brake-collars 42 .. 49, engaging the faces of discs 37 forming part of the spools, the brake-collars 44, 47 being telescopic and being provided with springs 52 for holding the set of brake-collars in engagement with the discs.
